Where do I find my App ID and API Key?

In Ontraport, go to **Administration** > **Integrations** > **Ontraport API Instructions and Key Manager**. Create a new key to get both the App ID and the API Key.

Can I target custom objects with these tools?

Currently, these tools are optimized for core objects like Contacts (0), Tasks (1), and Sequences (5). Support for other custom objects can be added by specifying their respective Object IDs in future updates.

Does this support creating new contacts?

Yes! Use the `create_contact` action. You can provide an email address along with optional first and last names to add a new person to your Ontraport CRM.
